I usually take a Retributor squad and take a rhino for them. Then deploy the squad beside the rhino and put the repentia behind it then in the movement phase embark. Then if everthing goes okay, I usually get them across the board enough to disembark and charge. It works a good chunk of the time. However,if playing against a drop pod army, if you don't get 1st turn, make sure you make it hard for them to land to close. This is how I us them most of the time but still depends on senerio.
